A network engineer has set up VRF-Lite on two routers where all the interfaces are in the same VRF. At a later time, a new loopback is added to Router 1, but it cannot ping any of the existing interfaces. Which two configurations enable the local or remote router to ping the loopback from any existing interface? (Choose two.)

adding a static route for the VRF that points to the global route table

adding the loopback to the VRF

adding dynamic routing between the two routers and advertising the loopback

adding the IP address of the loopback to the export route targets for the VRF

adding a static route for the VRF that points to the loopback interface

adding all interfaces to the global and VRF routing tables

Answer: A,B

Refer to the exhibit. After configuring GRE between two routers running OSPF that are connected to each other via a WAN link, a network engineer notices that the two routers cannot establish the GRE tunnel to begin the exchange of routing updates. What is the reason for this?

Either a firewall between the two routers or an ACL on the router is blocking IP protocol number 47.

Either a firewall between the two routers or an ACL on the router is blocking UDP 57.

Either a firewall between the two routers or an ACL on the router is blocking TCP 47.

Either a firewall between the two routers or an ACL on the router is blocking IP protocol number 57.

To identify all nodes for the node-local and link-local scopes, the following multicast addresses are defined:

FF01::1 (node-local scope all-nodes address)

FF02::1 (link-local scope all-nodes address)

To identify all routers for the node-local, link-local, and site-local scopes, the following multicast addresses are defined:

FF01::2 (node-local scope all-routers address)

FF02::2 (link-local scope all-routers address)

FF05::2 (site-local scope all-routers address)

Which two reductions are the correct reductions of the IPv6 address 2001:0d02:0000:0000:0014:0000:0000:0095? (Choose two)

A. 2001:0d02:::0014:::0095

B. 2001:d02::14::95

C. 2001:d02:0:0:14::95

D. 2001:d02::14:0:0:95

Answer: C,D Explanation:

We can’t use triple colons (:::) in IPv6 presentation. Also We can’t use double colons (::) twice. You can use it only once in any address because if two double colons are placed in the same address, there will be no way to identify the size of each block of 0s. Remember the following techniques to shorten an IPv6 address:

Omit leading 0s in the address field, so :0000 can be compressed to just :0 and :0d02 can be com-pressed to :d02 (but :1d00 can not be compressed to :1d)

Use double colons (::), but just once, to represent a contiguous block of 0s, so 2001:0d02:0000:0000:0014:0000:0000:0095 can be compressed to 2001:0d02::14:0:0:95 or 2001:0d02:0:0:14::95
